Contexts start with a “@” and cannot contain spaces.

Contexts are an idea that became popular when Getting Things Done (GTD) was published. In a GTD system, every task will have one. In todo.txt, they are entirely optional.

A context is for a second classification of tasks that is orthoginal to project. The traditional GTD contexts are for things like place or resource, such as @office or @phone. I prefer to use contexts to describe the type of work the task is about, such as @meeting, @analysis, or @deliverable. You might use contexts to denote clients, personal or business tasks, specific areas of your work, and so on.

SwiftoDo will highlight contexts in a separate color, so they stand out.

You can sort and filter by context, which is useful for organizing your task list and focusing on relevant tasks.
